In addition to their already released 2D Gamekit (and the more advanced 3D Gamekit), Unity have released three new Gamekits to their Unity Learn portal. The new gamekits include:
Each Gamekit includes a complete project downloadable from the Unity Asset store as well as a full step by step tutorial that average around 1 hour in duration. They are designed to introduce users to Unity without requiring art or programming ability. Each Gamekit is designed to be extended or customized by the user. Learn more about the new gamekits in the video below.
